Machine of the torus type



April 30, 1935. J. DEDIEU MACHINE OF THE TORUS TYPE Filed-Jan l2 1933 Patented Apr. 30, 1935 UNITED STATES PATENT OFFICE Application January 12, 1933, Serial No. 651,392 In France January 12, 1932 1 Claim.

The present invention relates to a system affording non-leaking conditions, and providing for the heating or cooling, in the case of machines of torus type, such as motors, compressors or pumps. The said system consists of a certain number of portions of a hollow torus, which will be designated as sleeves.

The said sleeves conform to: the shape of the torus-stator in which they are movable, and are given a circular motion by suitable elements which assure their connection with an adequate part of the rotor.

Each of the said sleeves has essentially for its object to afford non-leaking conditions for the working chambers which consist of the space between two pistons, or like parts, in all cases where such non-leaking conditions are required.

In the accompanying drawing, which shows by Way of example an embodiment of the invention:

Fig. 1 is an elevational view of a portion of a torus motor of circular section, provided with the non-leaking sleeve.

Fig. 2 is a section on the line 2--2 of Fig. 1.

Fig. 3 shows the device represented in Fig. 1,

on a smaller scale.

Fig. 4 is a perspective view of a sleeve, seen from the concave side.

Fig. 5 is a perspective view of a like sleeve,

seen from the convex side.

In the construction, the torus-shaped stator A, whose generatrix is a circle, consists of two halves or shells which are assembled by bolts or otherwise. In the said stator are mounted five sleeves E which in this particular case are connected by radial arms with the rotor F G.

As shown in Figs. 1, 2 and 3, the pistons B, mounted on the piston-rods C, are always engaged in two consecutive sleeves, and the various cycles take place within these latter. For this reason, the sleeves are provided with apertures H and I for admission and exhaust, which are arranged according to the conditions of the mo- 45 tor. In the particular case, in conformity with the motor arrangement adopted, two symmetrical slots J are formed in the sleeves to provide for the passage of the piston-rods.

The said sleeves may consist of a determined metal or alloy, and may receive the heat treatment which is required for the particular use, 5 and to the nature of the torus-shaped stator. In certain cases, the mounting of packing rings upon the outer wall of the sleeve is effected, as in the pistons oi the present construction.

It will be observed that the exchanges of heat 10 between the working chambers (suction, compression, explosion, expansion, discharge) are greatly facilitated by the displacement of the sleeve, and that the distribution of the temperatures in the stator is better effected for this reason. 15

The piston rods C which are joined to the rotor G by their interior extremities have lateral extensions C', to the extremities of which are mounted guiding elements, preferably in the form of rollers L. The rollers operate in a guide path 20 M conveniently placed in a fixed part of the motor. The guide path comprises relatively incurved parts which in forcing the rollers L to follow such path determine the angular movements of the rods C in relation to the rotor G. 25 The pistons are thus periodically and individuallly accelerated and retarded. Thus the working spaces between the pistons are alternately augmented and diminished.

I claim: 30

A machine of the torus type comprising a ringshaped stator, pistons movable in the stator, piston rods connected to the pistons and hinged at their inner end to the rotor, means for imparting to each of said rods oscillating motion 35 with respect to the rotor, sleeves movable in said stator between said pistons, radial arms provided on the rotor between said rods, said sleeves being rigidly connected to the outer ends of said arms, the ends of the pistons being slidable and tightly engaged in the adjacent sleeves, inlet and exhaust ports in said sleeves, and slots at the proximate ends of the inner side of the sleeves to permit the oscillating movement of the piston rods.
